“…Although HpmsE126 was considered as a minor QTL related to anthracnose resistance, in the current study, this marker was more efficient in identifying the anthracnose-resistant cultivars compared to the other markers. Other markers, HpmsE032 and HpmsE047, were proven to be closely related to the anthracnose resistance 26,27 . However, in this study, these markers were not able to determine the anthracnose resistance variance in the tested chili pepper cultivars.…”

Introduction: Colletotrichum species is responsible for anthracnose, a worldwide serious disease, causing an important loss in chili pepper production. Therefore, screening disease resistant and sensitive chili pepper cultivars in Vietnam is important not only for in-depth studies of disease resistance-associated molecular mechanisms but also for chili production improvement via molecular marker-assisted breeding in Vietnam. Methods: To this end, in this study, two Colletotrichum isolates were obtained from the infected fruits collected from chili pepper (Capsicum annuum) fields in Tra Vinh province. According to the morphology analysis and the sequencing results of the internal transcribed spacer (ITS) regions, these isolates were identified as C. scovillei and C. acutatum. In order to identify the anthracnose-resistant chili pepper cultivars, the pathogenicity test was conducted by infecting fully developed green fruits of eleven chili pepper cultivars with the two isolated Colletotrichum strains. Results: CN404 and HNCS were the two strongest anthracnose-resistant cultivars. Two chili pepper cultivars, TV3 and PN400, showed different resistance tendencies to each Colletotrichum isolates. Four different SSR molecular markers were used in this study to identify the potential molecular markers associated with anthracnose resistance traits in chili pepper cultivars. Among the four examined markers, HpmsE126 was detected in two anthracnose-resistant chili pepper cultivars, suggesting its close relation to the anthracnose resistance trait in chili pepper. Conclusion: Given that two of the three most anthracnose-resistant cultivars, CN404 and TV3, possess HpmsE126 marker, this marker can be used to detect anthracnose-resistant lines in chili pepper breeding in Vietnam.

“…The use of molecular markers is critical to expediting the speed of improvement programmes in order to fulfill the rising demand for increased capsicum yield and disease-resistant genotypes. Capsicum molecular markers [72] have been used for DNA fingerprinting, genetic diversity analysis, QTL analysis of important biotic stresses, and MAS [73].…”

Chipotle peppers were grown in America before being carried to Europe by Columbus. Capsicum breeding began with choosing wild species for desired characteristics, with additional development based on precision selection. To improve capsicum yields, traditional methods such as mass selection, pedigree, single-seed descent, backcrossing, and hybridization are being used. Capsicum has a high level of genetic diversity due to multiple new gene rearrangements. Capsicum fruits are high in nutrients that are beneficial to human health. As a result, the world market for and consumption of capsicum has lately grown. Capsicum breeding programmes aim to improve yield, biotic, abiotic resistance, and nutritional quality. Recent breakthroughs in capsicum breeding have included introgression, mutation breeding, polyploidy, haploidy, embryo rescue, and the use of genetic markers. Molecular technology has grown into an important tool that, when coupled with classic selection and hybridization procedures, has the potential to result in great success in an established capsicum genetic breeding programme.

“…Another mapping population obtained from C. baccatum 'PBC80' x 'CA1316, the map having 403 SNPs and 1270cM coverage (Struss et al, 2016). Suwor et al, 2017 conducted research on anthracnose disease resistance lines selection by marker assisted selection in introgressed lines PR1 (derived from PBC 932) and PR2 (derived from PBC 80) crossed to susceptible parent (PS). Validation of SCAR-Indel and SSR-HpmsE032 markers on F2 of the three way population revealed that their individual ability to predict correctly the resistant genotype was 65per cent; together it was 77 per cent.…”
